Application filed November 14, 1899. Serial No. 736,971. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE M. LIGHT, a citizen of the United States,residing at Pomeroy, in the county of Garfield and State of Washington,have invented a new and useful Land- Scraper, of which the following isa specification.

The invention relates to improvements in land-scrapers.

One object of the present invention is to improve the construction ofland-scrapers and to provide a simple and comparatively-inexpensive oneadapted for general leveling purposes, more especially for levelingplowed land, and capable of pulverizin g the clods and of destroying theweeds.

Another object of the invention is to enable the scraper-blades to bereadily set at the desired angle and to adjust the barrow-teeth andWeed-cutters simultaneously and to provide a seat for the accommodationof the driver.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a land-scraperconstructed in accordance with this invention, the truck for theaccommodation of the driver being in position. Fig. 2 is a longitudinalsectional view of the land-scraper. Fig. 3 is a detail perspective viewof the truck and the reach connections. Figs. 1, 5, and 6 are detailviews illustrating the manner of mounting the harroW-teeth.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

1 and 2 designate front and rear scraperblades, arranged in pairs, asclearly illustrated in Fig. 1 of the accompanying drawings, and formingseparate sections and connected by central and side longitudinal bars 3and 4, hinged at their front and rear ends 5 and 6 to the front and rearscraper-blades, whereby the latter are adapted to be arranged at thedesired inclination to produce the proper effect on the soil. Theconnecting-bars 3 and 4 are supported by bracing-rods 7 to form a frame,and these bracing-rods 7 are secured at their rear ends to the sidelongitudinal bars and at their front ends to the central longitudinalbar. The front and rear scraperblades 1 and 2 are of different lengthsin order to break joints and prevent the machine from leaving anyridges.

The longitudinal bars are provided with front and rear bearings 8 and 9,consisting of straps or clips and receiving shafts or rods 10 and 11,carrying barrow-teeth 12 and preferably constructed of tubular metal.The tubular metal is continuous at the bearings and is cut away betweenthe bearings at 13. The cut-away portions 13, which present concavefaces to the harroW-teeth, are provided at their upper and lower edgeswith notches 14:, receiving the teeth, which are secured in the notchesby eyebolts 15. The eyebolts 15 pass through perforations of the shaftsor rods and are provided at the front faces thereof With nuts 16. Thebarrow-teeth are preferably rectangular in cross-section, and the eyesof the bolts and the notches of the shafts or rods conform to theconfiguration of the teeth, whereby the latter are securely held at thedesired adjustment. By loosening the nuts of the eyebolts thebarrow-teeth may be adjusted vertically and arranged to penetrate thesoil to the desired depth. The front scraper-blades level the soil andpress the clods, which are broken by the harrow-teeth, and the rearscraper-blades smooth and pack the soil.

The front and rear scraper-blades are provided with upwardly-extendingarms 17 and 18, which are forked or bifurcated to receive an adjustableconnecting-rod or bar 18. The rear end of the latter is permanentlypivoted in'the fork or bifurcation of the rear arm,

and its front end is provided with a series of perforations 19 and isadj ustably secured by a fastening device 20 in the fork or bifurcationof the arm 17, which extends above the rear arm 18. By adjusting thefront end of the rod or bar 18 the blades 1 and 2 may be arranged inparallel planes or set at an angle to each other. This permits the frontscraperblades to be arranged at a slight inclination, nearly vertical,to adapt them forleveling the land and for breaking the lumps, and byarranging the rear scraper-blades at a greater inclination they willoperate to pack the soil after the same has been leveled by the frontscraper-blades.

The front and rear scraper-blades are adjusted simultaneously to changetheirinclination by means of an operating or shifting lever 21,fulcrumed at its lower end on the central connecting-bar 3 and connectedbetween its ends by a pivot 22 to the bar or rod 18. It is secured atthe desired adjustment by means of a ratchet 23 and a pawl or dog 24,the ratchet being mounted on the bar or rod 18 and the pawl or dog beingcarried by the operating or shifting lever. The rod or bar 18 isprovided in advance of the ratchet with a series of perforations 25,similar to the perforations 19 of the front end of the bar, to receive apivot 27 for adjustably connecting an arm 28 of the front rod or shaftto the bar or rod 18". This arm 28, which is suitably fixed to the frontrod or shaft, is provided with a series of perforations 29, and it isconnected at a point below the bar or rod 18 with a rear arm 30 by ashort connecting-bar 31. The rear arm 30 is fixed to the rear rod orshaft, and by this construction the harrow-teeth are adjustedsimultaneously with the scraper-blades.

Each rear scraper-blade is provided with rearwardly-extendingcutting-blades 32 designed for operating on weeds and having shortshanks 33 at their front ends, which are detachably secured to the rearfaces of the scraper-blades 2. The weed-cutting blades, which divergefrom the center of the scraperblade, are preferably constructed of flatmetal and have quarter-bends 33 adjacent to the shanks to set theirlower cutting edges at the proper angle, and their rear ends aretapered. The body portion of each weed-cutting blade is disposed at anangle to the short shank and inclines from its upper or back edge to itslower or cutting edge. ()ne of the central weed-cutting blades isprovided with a short blade 32, diverging from its body portion andoperating in the space between the two approximately-centralweed-cutting blades. The shank of the short blade 32 is arranged at anangle to the body portion and is secured to the rear face of thecontiguous central blade. The weed-cutting blades may be arranged tooperate in practically a horizontal plane, or they may be disposed at aninclination, and it will be readily apparent that by adjusting thescraper-blades the weed-cutting blades may be set in the desiredposition and held thereat.

In order to accommodate the driver, a rear truck is provided, and itconsists of a dropaxle 34 and carrying-wheels 35, having broadperipheries or rims to prevent them from sinking into the soil. Thedrop-axle is provided with a fiat top portion 34, having a series ofperforations 34 and connected with a rear reach-section 36, which isprovided at its front end with a segmental head 37, pivoted by a pin 38in a bifurcation 39 of a front reach-section 40. The rear reach-section,which is preferably constructed of flat metal, as shown, has its rearend resting upon the fiat portion of the axle and secured to the same bymeans of a suitable fastening device 3i, which also secures aspring-standard 41 of a seat 12 to the truck. The perforations of theflat top portion of the axle enable the position of the seat to bechanged from one side of the center to the other to locate it at thehigh side when the land-scraper is operating on a hillside, whereby thetruck may be properly balanced to prevent it from upsetting. The arms ofthe axle are connected with the rear section of the reach by braces orhounds 34:, secured to the reach bya bolt or other suitable fasteningdevice and provided at their rear ends with eyes which are linked intosuitable eyes 18 of the axle, and the latter is provided at one sidewith a rearwardly-extending step 49 to enable the operator to readilymount the truck.

The reach, which is composed of the front and rear sections, has itsjoint arranged in rear of the weed-cutting blades, and it is adapted topermit the machine to be turned easily without the wheels striking thesaid blades. The segmental head of the rear reach-section supports thesame in turning the machine and prevents the riding attachment or truckfrom twisting or upsetting.

In order to prevent the front and rear scraperblades from bindingagainst each other in turning the machine, the central section isprovided with fenders 50, consisting, substantially, of L-shaped platesor pieces secured to the front-and rear faces of the front and rearblades, at each end thereof, and form ing forwardly and rearwardlyprojecting fenders located in substantially the same plane as the edgesof the central blades and forming a bearing for the scraper-blades ofthe end sections.

The front reach-section 40 is forked to clear the central operatingmechanism, the fork being formed by two rods 40, provided at their frontends with depending arms 43, terminating in lower eyes 44:, which arelinked into suitable eyes 45 of a transverse bar 46, and the latter isalso connected by chains 47 with the front scraper-blades. Thetransverse bar 46 may be provided with any desired arrangement ofwhifi'ietrees for the attachment of the draft-animals.
